Balance training device

ABSTRACT

A balance training device includes a base having a connection bar which includes a transverse bar and a tilt bar. A transmission unit connected to the tilt bar and includes a pedal frame, a crank, a link, a shaft, a driving wheel, a belt and a fly wheel. The link unit is connected to the transverse bar and includes a driving plate, a first link, a second link, a third link, a fourth link and a seat frame. The seat frame includes a seat with two handles on two ends thereof and the link unit moves the user back and forth, and up and down so that the user&#39;s upper body is exercised. The pedal frame includes two pedals so that the user&#39;s feet are rested on the pedals and the user&#39;s body is moved like riding a horse.

FIELD OF THE INVENTION

The present invention relates to a balance training device which does not need electric power and moves back and forth and up and down.

BACKGROUND OF THE INVENTION

A conventional balance training device known to applicant is shown in FIG. 8 which includes base 61 with a head tube 62 in which a handlebar stem 63 is inserted, a seat bar 64 is connected to two U-shaped frames and a bottom bar 66 is located beneath the seat bar 64, a support bar 65 is connected between two respective ends of the seat bar 64 and the bottom bar 66, a seat is located on the seat bar 64, and a hydraulic cylinder 67 is connected between the support bar 66 and the a rear end of the base 61 so as to move the seat up and down.

Another balance training device is shown in FIGS. 9 and 10 and includes a base 7 on which a first fixing frame 71 and a second fixing frame 72 are connected, a bearing 83 is connected on the top of the first fixing frame 71 and a space 721 is defined in the second fixing frame 72 so that a fly wheel 86 is located in the space 721. A transmission mechanism 8 includes a crank 81 which includes two pedals 82 on two ends thereof and the bearing 83 is mounted to the crank 81. A chain wheel 84 and a belt wheel 85 are mounted on the crank 81, a belt driving the belt wheel 85 and the fly wheel 86. A seat assembly 9 includes a transverse bar 91 which has one end pivotably connected with a seat post 92 and the other end of the transverse bar 91 is connected with an upright tube 93 which includes a seat 94 connected thereon. A connection link 95 is connected between a protrusion 811 on the crank 81 and the transverse bar 91.

However, the device in FIG. 8 can only move up and down and cannot provide sufficient exercise to the users who quickly feel boring by the single mode of movement. The device disclosed in FIGS. 9 and 10 is more close to stationary bicycle which exercises the users' feet rather than the upper body.

The present invention intends to provide a balance training device which moves the user back and forth, and up and down so that the users have fun and get exercise during using the device.

The present invention relates to a balance training device which comprises a base having a first leg on which a frame is connected and a connection bar is connected between the frame and a second leg. The connection bar includes a transverse bar connected to the frame and a tilt bar connected to the second leg. A transmission unit has a pedal frame, a crank, a link, a shaft, a driving wheel, a belt and a fly wheel. The pedal frame has a securing portion on a first end thereof and two pedals are connected on two ends of a Y-shaped second end of the pedal frame. The crank has a first end pivotably connected to the pedal frame and a second end of the crank is pivotably connected with a first end of the link. A second end of the link is fixed to a first end of the shaft and a second end of the shaft extends through the driving wheel and the tilt bar. The belt is engaged with the driving wheel and an output axle of the fly wheel.

A link unit includes a driving plate, a first link, a second link, a third link, a fourth link and a seat frame. The driving plate has a first end secured to the shaft and a second end of the driving plate is pivotably connected with a first end of the first link.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the balance training device of the present invention comprises a base 1 having a first leg on which a frame 11 is connected and a connection bar 12 is connected between the frame 11 and a second leg. The first and second legs are put on the floor and the connection bar 12 includes a transverse bar 13 connected to the frame 11 and a tilt bar 14 connected to the second leg.

A transmission unit 2 includes an H-shaped pedal frame 21, a crank 22, a link 23, a shaft 24, a driving wheel 25, a belt 26 and a fly wheel 27. The fly wheel 27 is located between two side parts of the frame 11 which includes two side plates 111 on two sides thereof and an output axle 271 of the fly wheel 27 is engaged with the two side plates 111. The pedal frame 21 includes a U-shaped securing portion 211 on a first end thereof and two pedals 213 are connected on two ends of a Y-shaped second end of the pedal frame 21. Two protrusions 142 extend from two sides of the tilt bar 14 and the U-shaped securing portion 211 includes two connection holes 212 with which the protrusions 142 on the tilt bar 14 are engaged.

The crank 22 has a first end pivotably connected to a connection plate 214 on a mediate portion of the pedal frame 21 and a second end of the crank 22 is pivotably connected with a first end of the link 23. A second end of the link 23 is fixed to a first end of the shaft 24 and a second end of the shaft 24 extends through the driving wheel 25 and a through hole 142 defined through the tilt bar 14. A disk 241 is fixed to the shaft 24 and connected to the driving wheel 25. The belt 26 is engaged with the driving wheel 25 and the output axle 271 of the fly wheel 27.

A link unit 3 has a driving plate 31, a first link 32, a second link 33, a third link 34, a fourth link 35 and a seat frame 36. The driving plate 31 has a first end secured to the shaft 24 and a second end of the driving plate 31 is pivotably connected with a first end of the first link 32. A second end of the first link 32 is secured to a first end of the second link 33. A second end of the second link 33 is secured to a first end of the third link 34. A second end of the third link 34 is pivotably connected to a rear end of the transverse bar 13 and a first end of the fourth link 35 is pivotably connected to a front end of the transverse bar 13. The seat frame 36 is pivotably connected with the second link 33 and a second end of the fourth link 35. The seat frame 36 includes a seat 37 and two handles 361 are located on two ends of the seat 37. A case 4 is mounted to the base 1 and two respective dust covers 5 are mounted to the second link 33 and the fourth link 35.

As shown in FIGS. 4 to 6, when a user just sits on the seat 37, the seat frame 36, the second link 33, the third link 34 and the first link 32 are moved downward, and the pedals 213 are located at proper heights so that the user's feet conveniently put on the pedals 213. The driving plate 31 rotates the shaft 24 which rotates the driving wheel 25 and the link 23. The user applies a downward force on the pedals 213 to move the pedal frame 21 and the crank 22 downward, so that the link 23 rotates the shaft 24 and the driving wheel 25, and the fly wheel 27 is rotated by the belt 26. The shaft 24 moves the driving plate 31 to move the first link 32, the second link 33 an the third link 34 move forward and upward.

As shown in FIG. 7, the user moves the rear end of the seat frame 36 backward and upward, the front end of the seat frame 36 moves with the fourth link 35 forward and downward. This is similar to horse riding. On the other hand, the fly wheel 27 has an initial force when rotating and drives the driving wheel 25 via the belt 26, the first link 32, the second link 33 and the third link 34 are moved backward and downward by the shaft 24 and the driving plate 31. Therefore, the rear end of the seat frame 36 moves backward and downward, and the front end of the seat frame 36 moves with the fourth link 35 backward and upward. The movement exercises the upper body of the user in different directions just like riding a hose.
